Very cool battery but at 23 pounds it will make your go box go a lot slower.

I had an 18 amp-hour battery in my old go box, which was a contributing factor to my old go box being an epic fail. It was just too much. I ended up selling the barely-used battery at a hamfest for less than half of what I paid for it.

circuit breakers are super handy, not sure about over done (you need every advantage you can get), I have had issues with them not tripping fast enough in the past, or tripping at more than double the rating...they are good at not over currenting your batteries and keeping wires from melting, but they don't usually protect silicon devices very well (I usually use fast blowing fuses)that is why I had asked if he had tested them, I am pretty sure that someone makes ones that work for protecting silicon and if they are out there, I would love to know what ones they are.
